What is an optical illusion?

1.

Optical illusions are made to trick your brain into seeing something that is not there in reality.

When you look at something, your brain processes what you see and makes an image of the object you're looking at in your head.

Optical illusions use colours, patterns and lights to make it difficult for your brain to process exactly what you are seeing. That way your brain creates an image in your head that in reality is not there.

In the video the men demonstrate how an optical illusion can deceive you.
